Self-assembly of a molecular piston

A French and Chinese collaboration has designed a molecular piston that self-assembles to form a complex stable enough that disassembly is very slow compared to the sliding motion of the piston.

DNA molecular robots learn to walk in any direction along a branched track

In yet another in a long list of improvements to DNA based molecular machines, DNA molecular robots learn to walk in any direction along a branched track.

Molecular machine switches magnetic state at room temperature

Irradiation with two wavelengths of visible light switches the position of a nitrogen atom close to a nickel ion, and in the process switches the magnetic state of the nickel ion.

Advance could speed RNA nanotechnology

RNA nanostructures chemically modified to be resistant to degradation retain 3D structure and biological activity.

Scaling up from atomic assembly and individual nanodevices to macroscopic systems

51 years after Richard Feynman envisioned nanoscience in his famous address, “Plenty of Room at the Bottom,” four extraordinary researchers joined in a roundtable discussion of the future of nanoscience.

Update and summary of potential applications of medical nanorobotics

Robert A. Freitas Jr. has made available his chapter on nanorobotics from the book The Future of Aging.

Proteins designed 'from scratch' function in living cells

A significant fraction of small protein sequences designed only to fold into stable structures can substitute for missing natural proteins.

One-molecule robot to be presented at January's TEDxCaltech conference

A one-molecule robot capable of following a trail of chemical breadcrumbs will be presented at TEDxCaltech-Feynman’s Vision: The Next 50 Years.

Feynman Prizes in Nanotechnology Awarded by Foresight Institute

Palo Alto, CA – December 20, 2010 – The Foresight Institute, a nanotechnology education and public policy think tank based in Palo Alto, has announced the winners of the prestigious 2010 Foresight Institute Feynman Prizes in Nanotechnology. Established in 1993 in honor of Nobel Prize winner Richard Feynman, two $5,000 prizes are awarded in two… Continue reading Feynman Prizes in Nanotechnology Awarded by Foresight Institute

Theoretical analysis of powering nanorobots with blood glucose and oxygen

Hogg and Freitas provide a theoretical analysis of the power constraints when nanorobots rely entirely on ambient bloodstream oxygen and glucose and identify aspects of nanorobot design that significantly affect available power.
